If an amp is bridged, it see's twice the load
To simplify if a bridged amp is connected to a 4ohm sub' the amp would see a 2ohm load, is this right ? or have I got it @rse about.
thanks GK |

A 4-ohm speaker is never a 2-ohm load; it's merely equivalent power (200@4 = 400@2, assuming 100% efficiency).
This is commonly stated because an amp should be 2-ohm stable (x2) in order to handle the bridged 4-ohm load.

a bridged amp "sees" half the actual load.
if the amp is 2 ohm stable in stereo, it will be 4 ohm stable when bridged.
this is due to inverting one of the channels to use the combined power of both channels for one load.
